Abstract
SummaryCrop scale experiments were carried out in 1998/99 to investigate the individual and interactive effects of vapour pressure deficit (vpd), root-zone temperature (RZT) and potassium nutrient feed concentration on the accumulation of Ca and K in shoot tissues, vegetative growth, fruit yield and quality in tomato (Lycopersicon esculentum Mill). RZT and K nutrition had no detectable effect on growth but high K nutrition (10.mM) compared with the low (4.mM) increased the accumulation of K in the leaves and older fruits. In contrast, severe deficiencies of K were detected in young expanding lea¯ets (0.66±0.75%) near to the shoot apex under high (0.1.kPa vpd) compared with control humidity (1.50±2.03%; 0.5.kPa vpd). The accumulation of Ca was either unaffected or increased in leaf tissue at high humidity. Fruits developing on trusses in the top half of the shoot had markedly lower K concentrations under high humidity. In contrast the concentration of Ca was increased in fruit. The area of individual leave...
